Motor action occurs when electromagnetic energy (electricity) is converted into mechanical energy (rotation) by the fan motor. The fan then turns and air moves through t…he device. Electromagnetic energy (that same electricity) is also converted into thermal energy in the heating element, and from there the heat is transferred into the air as it passes by.

A hair-dryer doesn't produce energy. It consumes electrical energy, and uses it first to raise the temperature of some air, and then to impart kinetic energy to the heated… air and blow it out the end of the hair dryer. The rate at which the hair dryer uses electrical energy is usually marked prominently on the appliance ... typically anywhere from a few hundred watts to 1200 or 1300 watts.

Electricity is converted partially in to heat by means of a heating element built in the dryer. Another part of electricity is converted to a circular motion of an electri…c motor with a fan, which forces the hot air out of the hairdryer.
